A stoic person is someone who stays calm and doesn't get easily upset or excited, even when things are difficult or bad.
Imagine your friend just got into a car accident, but they're not freaking out. They might have broken bones, but they're still thinking clearly and helping others at the scene. That's a pretty stoic person - staying cool under pressure, no matter what happens. People who are naturally stoic often get admired for their calmness in tough situations.
Proponent of stoicism, a school of thought, from in 300 B.C.E. up to about the time of Marcus Aurelius, who holds that by cultivating an understanding of the logos, or natural law, one can be free of suffering.
Of or relating to the Stoics or their ideas.
